I purchased a brand new Gigabyte EP45-UD3LR, but when I put together the computer and started it, the music seemed to crackle. I taught it was some driver problem, so I reinstalled Windows 7 x64. However, after reinstall the problem was still present.
My default music player is foobar2000. MP3s crackle only very rarely (but they do), however the problem is much worse with WMA files and MMS streams, because they crackle almost at every second. KMPlayer seems to crackle randomly on avi or mkv files as well. The problem is much worse with VLC: the sound makes 0.5 second stops at every 3-5 seconds.
I googled the issue and tried every possible fix:
- Changed sound output format from Studio Quality to CD Quality. No effect.
- Since my CPU was overclocked to 3.6 GHz from 2.6 GHz, I disabled the overclocking, but that didn't fix it neither.
- I tried changing the RAMs. Nada.
- Tried using the drivers installed by Windows, instead the ones from Realtek's website. The sounds seems to be somewhat quieter, and doesn't crackle that much with VLC, but still does.
- I did CPU and memory tests, and they're stable.
The sound equipment is a Genius 5.1, but it doesn't crackle with other sound source. (set-top box)
DCP Latency checker shows an average of 5500μs latency, and an absolute of 5952μs. All the bars are red. I tried disabling drivers, but that did not solve it either. Also, it is on a fresh Windows 7 installation.
Unfortunately I don't have a sound card to test it.
What could I try to do?
EDIT: I fixed the sound problems by turning off C1E and EIST from the BIOS, then turning off the Gigabyte Dynamic Energy Saver in Windows.
